苹果矮化密植栽培具有结果早,产量高,省工,易管理等优点。为了使矮化密植栽培技术在苹果生产上更好地发挥优势,在栽培管理过程中,应抓好以下几个技术关键:1、选用适于密植栽培的品种。目前最适于密植的品种,有金冠、秦冠、胜利、鸡冠,辽伏及短枝型芽变品种。较适于密植的品种,有赤阳、葵花、富士等。国光、白龙、国庆、红元帅、红星、红冠等品种,因为长势较强,成花晚、早期产量低,较难用于密植栽培。2、选用适宜的砧木类型。据调查,山荆子,海棠、沙果等,都是进行乔砧密植的良好砧木。辽宁、山东、河北、河南、山西等地实践证明,M_7是良好的矮化砧木,适应性强,繁殖较容易,同各品种的嫁接亲和力强,长势中庸,树体矮化,早果丰产,是 Apple dwarf planting cultivation results early, high yield, labor, easy to manage and so on. In order to make dwarfing and close cultivation techniques play a better role in apple production, in the process of cultivation and management, we should grasp the following key technologies: 1, Selection of varieties suitable for close planting. Currently most suitable for close planting varieties, the Golden Delicious, Qin Guan, victory, Cigar, Liaowu and spur-type varieties. More suitable for close planting varieties, there are red sunflower, Fuji and so on. Guoguang, Bailong, National Day, Red Marshal, Red Star, Red Crown and other varieties, because of strong growth, late flowering, early low yield, harder for close planting. 2, choose the appropriate type of rootstock. According to the survey, Shan Jing Zi, Begonia, sand fruit, etc., are good for planting anvil rootstocks anvil. It has been proved by practice in Liaoning, Shandong, Hebei, Henan and Shanxi that M_7 is a good dwarfing rootstock, which has strong adaptability and easy multiplication. It has strong affinity with all varieties of grafting, moderate growth, dwarfing trees, Yes
